Epic quality beacon transmission efficiency is 2.09 instead of the reported 2.1

It's not a huge deal, but it definitely seems like the UI is wrong that the efficiency is 2.1, it's actually 2.09.

Seems like imprecision due to rounding. There is much more severe cases reported here on the forums …

one example being: viewtopic.php?p=624251#p624251
where 0.25 is being rounded to 0.3

2.1 in computer is exactly 2.0999999046325684, it's truncate to 2.09, not round to 2.10
why use truncate here, not round?

We do not truncate or round. The display value is converted to a string using printf(“%g”, value) and what you see is what you see. The actual beacon computation uses the raw float value, the display shows what it wants to show and it’s not worth the pain and agony to try to make them not show more decimal places.

Was something like printf("%.3g", value) considered and not used in the end because it created undesired results in other edge cases?
